SAMPSEL
Sample Time Selection
When SAMPSEL = 0, the value of SAMPx[2:0] is set as follows:
000: 1.5 cycles 100: 41.5 cycles
001: 7.5 cycles 101: 55.5 cycles
010: 13.5 cycles 110: 71.5 cycles
011: 28.5 cycles 111: 239.5 cycles
When SAMPSEL = 1, the value of SAMPx[2:0] is set as follows:
000: 1.5 cycles 100: 19.5 cycles
001: 2.5 cycles 101: 61.5 cycles
010: 4.5 cycles 110: 181.5 cycles
011: 7.5 cycles 111: 601.5 cycles
